. BUMP-can.

To all whom 'it may concern: I

Be it known that I, HARRY S. HART, a citizen of the United Statesresiding at Chicage, in the county of dook and vState of Illinois, haveinvented certain new and user ful Improvements in Dump-Cars, of whichthe following is a specification.

The object of my invention is to provide a car of the t pe known astheHart convertible car7 with movable sides so formed that they may beeither adjusted to a vertical position or to an inwardly and downwardlyinclining position. Hart convertible cars are illustrated in PatentsNos. 689,583 granted to Harry S. Hart, December 24, 1901, and 827,632,Harry S. Hart and others, July 31, 1906. Cars of the type to which myinvention is ap lied are provided with a central 'lon itu nal. ho per,flat floor sections ex'ten ing outwar ly from'the hopper to the sides ofthe car and vertical sides and adjustable ends. Means are provided forcovering the central hopper in order to transform the car into anordinary gondola car,v

and to so adjust the parts as to uncover the central hopper, to inelinethe ends inwardly toward the central hopper, and in some instances toprovide upward prolongations of the side of the central hopper. Thenature of my improvement in these cars 'will be apparent from thefollowing description and claims, taken in connection with theaccompanying drawings. This application is drawn to subject-mater shownoriginally and described in my co- 'iending application Serial No.519,865, filed eptember 27, 1909, and is limited to subject-mattereliminated from said application, andpresented in this application as adivision of said copending application.

In the drawingsJ Figure 1 is a cross sectional view of a car embodyingmy invention. Fig. 2 is a detail View of the structure adjacent oneofthe side stakes looking from the inside of the car. Fig. 3 is a planview of the corner structure. Fig. 4 is a cross section, taken throughone of the telescoping side stakes. Fig. 5 is a detail view of thestructure at the top of one of the side stakes,`

the parts being shown in section on line 5 of Fig. 1. F i0'. 6 is aSectional view through the side stake shown in Fig. 5 and taken at rightangles thereto.

hinged at their upper edges. It ismy pres ent purpose to so arrange thestructure that these doors maybe moved inwardly on their hinges to slopein the direction of the walls of the hopper bottom to form prolongationsthereof. i I

Referring to Fig. 1, the central longitudinal hopper is formed of astationary wall 1 and a wal12 hinged to the underframe of the car. .Achain t attached to the hinged wall 2 in connection with a windin shaft5 affords means for opening ancF closing the hinged wall or door 2.Horizontal floor sec tions 6 and 7 extend outwardly rrom the centrallongitu'dinal hopper to the sides of the ear. Door or floor sections 8and 9 are hinged to the central longitudinal sill 10 and may be adjustedeither to cover the central lon itudinal hopper as shown in full linesat t e right of Fig. 1, or m'ay be moved upwardly to leave the hop erunobstructed, as indicated in the case of t e door 8 at the left of Fi1, the door 9 being shown in a correspomng position in dotted lines.

The sdestakes are so formed that they may be extended or shortened, atelescoping structure being shown in the'present n- 'side ot' thechannel11 and serve to guide the 'stake section 13 and to hold it in place.Mounted upon the upper ends of the stake sections 12 are side railswhich extend throughout the length of the car. Each of these side railsconssts of zi timber 14 to the- The main body of the side stake' lowerside of which is fittedan I-bean 15. V

The side rails are secured to the side stake sections 12 by means ofangle irons 16 bolted, 'espectively, to the side stakes and to the siderails.

Between the side stakes, doors 17 are hinged to the side rails, thehinge Straps 18 upon the doors engaging Ushaped hinflfe .members 19which depend fronrthc si e rails. The doors 17 are of such size as tofill the spaces between the side stakes and between the side rails and'loor ofthecar.

At the right of Fig. 1, I have shown the doors 17 in`a verticalposition, the side rails being elevated and the side staltes in theirelongated position. In this position of the parts the side rails areheld elevated by the doors which extend downwardly in a verticaldirection from them. and the doors are held from opening outwardly byany convenient locking mechanism, such as that ordinarily employed incars of this type and illustrated in Patent 827,632 referred to.. VVhenthe sides occupy the vertical positionrshmvn at the right of Fig. 1, thecentral doors 8 and 9 will be moved downwardly to cover the centralhopper as illustratcd in the case of the door f) at the right-hand ofthat View. When so adjusted the car is adapted for use as an ordinarygondola car.

l/Vhen it is desired to use the car as a center dump car, the doors 8and S) may be moved to their upwardly projecting position as shown inthe case of the door S and in dotted lines in the case of tho door i),and fastcned in that position by means of a swinging bolt 20 or otherconvenient means. The doors 17 will then be moved inwardly, thuspermitting the side rails 14 to drop to their lower position, thismovement being permitted by the telescoping of the side stakes. As incars of this type, the adjustment for central dump will be completed byadjusting the ends to slopc inwardly toward the central hopper. Thisfeature, however, I have not illustrated as itforms no part of mypresent invention.

Unless s ome' provision be adopted, spaces would be left between thedoors 17 when adjusted to the position shown at the left of Fig. l, suchspaces beingl of the width ot' the side stakes which separate the doors17. I have therefore shown aprons 22 hung upon the loops 19 which suport the doors 17, these aprons being o. somewhat greater Width than theside stakes. and lapping over the adjoining edges of the doors 17. :Thisstructure is clearly illustrated in Fig. 2. lThe upper ends'of theaprons 22 are provided with eyelets, these eyelets engaging the loops19. l/Vhcn the doors 17 are moved inwardly, to the position shown at theleft of Fig. 2, the aprons 22 will be carried with them, thus affordinga closure between the spaces between the doors 17. `When the doors 17are adjusted vertically as shown at the right of Fig. 1, the aprons 22will hang fiat against the doors7 and when the lower edges of the doorsare moved outwardly, the aprons will be left behind and lying againstthe inner faces of kthe side stakcs.

The lowering of the sides which vis caused by the adjustment shown atthe left of 'Fig. 1 possesses the advantage of rendering the car easierto load by means of a stea shovel orv otherwise: The side rail lit may1n each of its adjusted positions be connected tp the end wall 31 of thecar by any convenient means, such as a corner clamp 30 bolted to eeessithe side rail and end waii or to one of these parts. A structure of thischaracter is illustrated in Fig. 3.

While l have described a specific mode of carrying out my invention, itiWill be apparent that the application of the principle is not dependentupon the use of the particular mmsiruction herein shown and described.
